After an artillery push, most of the biters attack the source of the artillery push. Unfortunately some of them lose interest and just wander around in the cleared territory. This mod adds a building which baits these wandering biters into attacking the building. If you protect this building with some turrets, this gives you an easy way to clean up these wandering biters after a push, so you can really claim your new territory without being worried of guerrilla attacks.
Balancing is intentionally expensive, because this is a late game thing to fix an annoyance for mega-base building.
